Which specimen that we have dissected so far seems most like humans? Why?

  We already dissected several specimen in our biology class, and frog is the speciman that seems most like humans so far.  One of the main reasons is that both frog and human are vertebrate with a cephalizated nervous system.  In addition, frogs have kidneys, gall bladders, livers, spleens, and livers just like what humans have.  Therefore, frogs and humans are close relatives.  Both humans and frogs eat meat, so this can be another reason.  Frogs also have a complete digestive system, and humans have, too.  Unlike some other animals, frogs have lungs instead gills, and the humans do have lungs.  Finally, the similarities between humans and frogs are much more than the differences between them.
